DXR-701

Installation
Instructions

The DXR-701 is a digital receiver with an isolated relay output designed for use 
with Linear’s DX Format transmitters. This receiver can be used in a variety 
of  remote  control  applications.  When  the  receiver  detects  a  signal  from  a 
transmitter programmed into its memory, the relay output activates. The relay 
has four optional output configurations.

In a typical installation, the receiver is connected to an alarm control panel, door 
strike, camera, high current relay or some other device. A transmitter is used to 
activate or control the device. The receiver should be mounted with the supplied 
mounting bracket indoors or inside a weather resistant non-metallic housing.

The  digital  DX  code  format  features  over  a  million  possible  codes. The  DX 
transmitters are precoded at the factory to unique codes, so no field coding 
is required. Receivers must be programmed to the transmitter’s code before 
system  testing  and  operation.  Up  to  32  transmitters  can  be  programmed 
into  the  receiver’s  memory.  The  memory  is  retained,  even  without  power.
The unit can be powered from a 11-17 VDC or 12-16 VAC power source. The 
relay’s normally open and normally closed contacts can switch up to 1 amp at 
24 volts AC/DC.

Cutting  jumpers  select  how  the  relay  activates.  The  factory  setting  causes 
the  relay  to  engage  for  four  seconds  each  activation.  Optionally,  the  relay 
can be set to engage for one second, toggle on with one activation then off 
with  the  next,  or  latch  engaged  until  reset  by  pressing  the  program  button.

A  nine-inch  wire  lead  serves  as  the  receiver’s  antenna.  The  red  program 
indicator  lights  during  RF  reception. The  installer  can  verify  that  signals  are 
being sent from transmitters and diagnose interference problems by viewing 
the indicator. The indicator also lights during memory programming/erasing and 
flashes to count the number of transmitters in memory. The program button and

Linear radio controls provide a reliable communications link and fill an important need in portable 
wireless signalling. However, there are some limitations which must be observed.
•  For U.S. installations only: The radios are required to comply with FCC Rules and Regulations 

as Part 15 devices. As such, they have limited transmitter power and therefore limited range.

•  A receiver cannot respond to more than one transmitted signal at a time and may be blocked 

by radio signals that occur on or near their operating frequencies, regardless of code settings. 

•  Changes or modifications to the device may void FCC compliance.
•  Infrequently  used  radio  links  should  be  tested  regularly  to  protect  against  undetected 

interference or fault.

•  A general knowledge of radio and its vagaries should be gained prior to acting as a wholesale 

distributor or dealer, and these facts should be communicated to the ultimate users.
